AI Analysis
Technical Summary
ArcadeDB before version 26.8.1 (specifically versions <= 26.7.3) has a missing authorization vulnerability in the DELETE FUNCTION SQL statement. The DeleteFunctionStatement.executeSimple method unregisters and persists the deletion of server-side functions without performing the required checkPermissionsOnDatabase (UPDATE_SCHEMA) authorization check. This allows any user with database access to execute DELETE FUNCTION commands via the command API (POST /api/v1/command/{db}) to permanently remove any registered server-side function, including those that implement security-relevant logic, thereby impacting the integrity and availability of the database.
Potential Impact
Any user with access to the database can delete server-side functions without authorization, which may lead to removal of critical security functions. This compromises the integrity and availability of the database system by allowing unauthorized modification of its schema and logic.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. The vulnerability is fixed in ArcadeDB version 26.8.1. Until an official fix is confirmed, restrict database access to trusted users only to mitigate risk.
